WebQuasi-concave functions and concave functions. I If f is concave, then it is quasi-concave, so you might start by checking for concavity. I If f is a monotonic transformation of a concave function, it is quasi-concave. This also means that if a monotonic transformation of f is concave, then f is concave. I Example: Check whether the f(x;y) = xy ... http://wikiludia.mathematik.uni-muenchen.de/wiki/index.php?title=Quasi-konkav
WebHowever, strictly quasi concave function may as well be strictly quasi convex. Example 1.3: If f is strictly increasing function on .That is if xy! implies f x f y( ) ( )! then is both strictly quasi-concave and strictly quasi-convex on. Theorem 1.4 Let be a quasi-concave function defined on the convex set n T . WebIn convex analysis, a non-negative function f : R n → R + is logarithmically concave (or log-concave for short) if its domain is a convex set, and if it satisfies the inequality (+ ()) ()for …
WebIn mathematics, a real-valued function is called convex if the line segment between any two distinct points on the graph of the function lies above the graph between the two points. Equivalently, a function is convex if its epigraph (the set of points on or above the graph of the function) is a convex set.A twice-differentiable function of a single variable is convex … Webjonka : German - English translations and synonyms (BEOLINGUS Online dictionary, TU Chemnitz)
In mathematics, a concave function is the negative of a convex function. A concave function is also synonymously called concave downwards, concave down, convex upwards, convex cap, or upper convex.
